what is equifax secure certificate authority

How does it work: Found one SSL certificate two different chains and two different root CAs

I bought an SSL Certificate from GeoTrust.

On checking the certificate chain on different Devices I found two different chains. Both chain are valid!

On chain ends in Root-CA C=US, O=Equifax, OU=Equifax Secure Certificate Authority and the other one in Root-CA C=US, O=GeoTrust Inc. CN=GeoTrust Global CA.

The different between this chains are in the first chain "GeoTrust Global CA" is signed by "Equifax Secure Certificate Authority" and in at the second "GeoTrust Global CA" is self-signed. But in both chain the Fingerprint of "GeoTrust Global CA"

is "C0:7A:98:68:8D:89:FB:AB:05:64:0C:11:7D:AA:7D:65:B8:CA:CC:4E", only the Serial Number is different.

How is this possible? I thought ssl certificates, the fingerprints of them and the cahins are unique!
